I own almost a dozen pairs of Perry Ellis slacks. This product, however, runs very, very small at the waist...at least one complete size smaller (almost 3 inches!!). They were so tight I double-checked both the cardboard tags and the fabric tag to see if there had been a shipping mistake. It's a great looking product, but do yourself a favor and order the next highest size, and consider purchasing two sizes higher if you are a borderline fit.
